[Xedra Evolved] Add goblin fruit map special

Summary

Mods "[Xedra Evolved] Add goblin fruit map special"

Purpose of change

“We must not look at goblin men,
We must not buy their fruits:
Who knows upon what soil they fed
Their hungry thirsty roots?”

Goblin fruits have strange effects and are a fun little addition (says me, who added them), but at the moment they're limited to only Paraclesian fae because they only spawn through spells. So, there should be a way to get them out in the world.

Describe the solution

Add a map special that has some strange plants which give goblin fruits when harvested. The plants fruit in random seasons (accomplished by having four plants that look the same, one for each season). The plants just look like bushes, but they're easy to find in the forest because they glow.

Because it's currently not possible for a plant to pick an item from a list, the plants give you "mysterious fruits," which are goblin fruits in a thick shell. You have to crack the shell to get the fruit. The "mysterious fruit" has a spoil timer of 2 months, but actual goblin fruits spoil in 3 days.

Once variants are possible for terrain, these plants are going to get a bunch of wild descriptions.

Describe alternatives you've considered

Testing

Bushes spawn. They all look the same but they're variable in what seasons they can be harvested in, so it's always worthwhile to go back to a previous map special and see if new goblin fruit are ready.

At the moment, the fruit are rotten when you crack open the mysterious fruit, but #72194 will fix that.
